NUT-SPLITTER.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed August 21, 1905. Serial No. 275,070.,

To all whom it may con/007%:

Be it known that I, WILLIAM G. BROWN, a citizen of the United States, residing at Carlsbad, in the county of Eddy, Territory of New Mexico, have invented certain new and useful Improvements in Nut-Splitters, of which the following is a specification.

My invention is an improved machine for splitting nuts to facilitate the removal thereof from bolts; and it consists in the construction and combination of devices hereinafter described and claimed.

In the accompanying drawings, Figure 1 is an elevation, partly in section, of a nut-splitter embodying my improvements. Fig. 2 is partly an elevation at right angles to Fig. 1 and partly a sectional view on the plane indicated by the line a a of Fig; 1.

The back plate 1 is preferably of the form here shown, has its broadened end offset, as at 2, and its narrowed portion is provided with reinforcing-ribs 3 on its outer side. On its inner side at its narrowed end said plate is formed with a lug 4, and at a suitable distance from said lug are a pair of parallel longitudinal guide-lugs 5.

A chisel 6 operates between the pair of guidelugs and is provided with a broadened base having a pair of sockets 7. A pair of operating handles or levers 8 are formed or. provided with intermeshing gears 9, which are concentric with their pivot-bolts 10 and are also formed or provided with eccentrics 11. Links 12 have openings at one end engaged by and in which the eccentrics turn, the opposite ends of the links being formed with pivot-heads 13, which are fitted in the sockets 7 of the chisel-base, so that the said links serve to connect the eccentrics on the handles to the chisel.

The gears 9 cause the handle-levers to move in unison, and the eccentrics and links cause the angular movement of the handle-levers to impart reciprocating movement to the chisel,

the latter being moved so that its sharpened edge approaches the lug 1 as the handle-levers are closed'and recedes therefrom as the handle-levers are opened.

A face-plate 14: is secured inplace by the bolts 10, which pivot the handle-levers, and the screws 15, which enter threaded openings in the guide-lugs. A block 16 is secured to the plate 1 at a point between the guide-lugs and the lug 4 by means of a screw 17, which operates in a slot 18 in said plate. An adjusting-screw 19, which operates in a threaded opening in the lug 4, bears against the outer side of the said block.

In using the machine the nut to be split (indicated at b) is caused to bear against the block 16, a slot 20 in the plate 1 serving to clear the projecting end of the bolt 0, and the handlelevers being closed the chisel is caused to split the nut, as will be understood.

Having thus described my invention, 1 claim 1. A nut-splitter having a longitudinallymovable chisel, a pair of intergeared, angularly-movable levers, eccentric cams on the said levers, and links connecting said eccentric cams to the chisel, substantially as described.

2. A nut-splitter having a base-plate provided with a pair of guide-lugs and a stop-lug, a chisel guided by the guide-lugs, a block, means to secure and adjust the same toward and from the stop-lug, a pair of intergeared levers pivoted to the baseplate, and each provided with an eccentric cam, and links con necting the eccentric cams to the chisel, substantially as described.

In testimony whereof I hereunto affix my signature in the presence of two subscribing witnesses.

W. G. BROWN.
